The donation angle really is a sticky, complicated situation.
DFC will charge you about $2500 to "donate" your timeshare. It will likely be more if DFC feels that it will be difficult to quickly turn around and sell.
A cheaper method, if you are willing to do a bit of work, is to give it away and perhaps offer to pay closing costs about ($300) and the following year's maintenance fees. You can advertise here on RedWeek, My Resort Network, E-bay, and/or Timeshare Users Group (TUG).
